I don't have a Kubota tiller, but I lost 2 blades and I took an example to a local agricultural supply dealer (Eastern Farm Machinery in Guelph, Ontario) and I said I need some of these and he found something which fit.
Vic,
Thanks for the reply. I'll take an inventory of the ones I need to replace and get ahold of you when I get back to the USA. Can you give out a personal e-mail or phone number tocontact you or should I just go through the website. Thanks again.
